Actually, this is not a new request but a reply to a thread that was started
back in March 2013 by Hong Sun:


Perhaps all we have to do is to say we already discussed it!? We could also
add a sentence clarifying that implementations do not have to store language
tags in normalized form. If we want to go a step further I think we could
even modify the MAY statement from

  Lexical representations of language tags MAY be converted to lower case.


  Lexical representations of language tags MAY be converted to lower case
  or formatted according [BCP47].

MAY statements do not carry much weight as they describe completely optional
"features". The statement above just highlights that implementations can
legitimately change the lexical representation without affecting the meaning
of a statement. I thus do not see this as a change to RDF but a
clarification. Does anyone disagree?
